my 4g63T having problem with the throttle body, i can't find that thing in the market place....my question here...is it fit if i use another throttle body from GSR or anything else that can fit.....i'm blurr.... help me solve my problem here....
Boost goes up nicely to 0.5 bar at 3000rpm but then starts to drop to 0.3 bar starting 3000rpm until 4500rpm. After that it fluctuates about between 0.4 and 0.3 bar until 6000rpm. Any idea why? Boost leak?
